This website This website is my design completely. A combination of Javascript, HTML5 and CSS3 is used. The goal was to build a representive website with the latest technology. Part of this was to learn about animations. Have you already tried to move your mouse or finger over my name? This is not the first animation made, please click the link below for an other example.Animation demoTV's server v3.10 TV's server is a platform for network services. It's completely written in Assembly (x86 and x64) and because of that it is small in size with great performance. The source can be downloaded and edited for free. Network service can be added through a plug-in system that can be written in the programming language Assembly and C. Examples of a plug-in with source can be downloaded.Download | More informationCPUID viewA program that enumerates processor information and functionality, it will let you know which functionality the processor in your computer is supporting. The source and binaries can be downloaded and edited for free.DownloadPEToolPETool is written to research the PE-file format (Windows application). One of the possibilities it's offering is to display all the information of the PE-header in readable format on the screen. Another possibility is to recover a PE-header or to expand applications. This can be done by adding compiled machine code to the program and move the entrypoint to this peace of code.Download | More informationMemory analyserIn commission by the Netherlands Forensic Institute we researched (as a group) if a browser leaves traceable data on the hard drive after surfing on the web using a private session. I researched the memory. To test my findings I created this program called Memory Analyser, that can be used to find the navigation and cookies of a browser. It's a Windows program that tries to find structures and URLs on live memory or on memory dumps taken earlier. The browsers Internet Explorer, Safari, Firefox and Chrome where examined. The results of this research can also be downloaded (this document is written in Dutch).Download | More informationSecure phoneI questioned myself: is it possible to message each other without being eavesdropped. To answer this question I tried to develop a mobile phone. This means I put together hardware and wrote the software. This telephone could send text messages with XOR-encryption and an infinite, once to be used, key. The prototype was a success, however, my interests went in a different direction and it never came to production.Digital exam environmentDuring my time as a teacher, the university I worked for wanted a way to take programming examinations in a digital and safe way. I took responsibility for this task. One important condition was that the students were not able to cheat, with the Internet as the biggest threat. As a result I built a costumed Linux kernel with no network drivers presented. This kernel was combined with desktop and develop software to be written to a USB-key as a bootable USB stick. The students booted up their own laptop with this USB-key in order to safeley make the programming exam.Examine toolAs a result of the Digital exam environment (see previous project), teachers received dozens of digital tests. These tests existed of lots of directories, with multiple assignments and files. Because of this, half of the time was used for organizing what was to be examined. I created this program to ease up this process. Opening the correct files with, by the teacher, assigned tools. Another possibility is to program keystrokes with variables to be send to open windows. Combined, this tool could automate almost every organising task, which let the teacher actually examine the tests. Stop animationC#!...Java|HTML

PETool
PETool is written to research the PE-file format (Windows application). One of the possibilities it's offering is to display all the information of the PE-header in readable format on the screen. Another possibility is to recover a PE-header or to expand applications. This can be done by adding compiled machine code to the program and move the entrypoint to this peace of code..

This tool works with 32-bit windows applications only, it doesn't work with 64-bit applications. The possible instructions that can be used in this program can be requested by typing the command help, to request a specific documentation from a command, type in help followed by a space and command name.

Memory Analyser
In commission by the Netherlands Forensic Institute we researched (as a group) if a browser leaves traceable data on the hard drive after surfing on the web using a private session. I researched the memory. To test my findings I created this program called Memory Analyser, that can be used to find the navigation and cookies of a browser. It's a Windows program that tries to find structures and URLs on live memory or on memory dumps taken earlier. The browsers Internet Explorer, Safari, Firefox and Chrome where examined. The results of this research can also be downloaded (this document is written in Dutch).

The research took place mid 2013 which means the browsers used in this research are outdated. Because of that, some finding are not representive for the today's browsers, however, some findings still are as of 2018.

TeachingWorking from 2015 until 2018 I really enjoyed having contact with the students. Guiding the students, teaching them and admiring their works of art is what I loved doing. I did this at University of Applied Sciences at Leiden. My tasks included the following.

Giving lectures and seminars

Recording video lectures

Designing education

Creating digital exam environment

Guiding students as a student career counselor

CertificatesDuring my teaching, I took several courses.

Basiskwalificatie Didactische Bekwaamheid (BDB)official Dutch diploma which certifies a person as an official University of Applied Sciences teacher.

Basiskwalificatie Examinering (BKE) diploma which certifies a person to make and examine tests at the University of Applied Sciences at Leiden.

Lectures (dutch recordings)

Below are some recorded lectures of me. The first one is in front of a lecture hall, the other without audience. The videos are Dutch spoken

During my time as a teacher I found out I really like having contact with other people, helping them and getting to know them. Because of this, I started studying Psychology as a home study in 2017. It's really interesting and also new for me, since I've always have been working in the IT field.Hi and welcome,
